AUTO T'I-IEFT SIGNAL.

Application led October 1, 1920.` Serial No. 414,036.

To all whom t may concern.'

Be it known that we, RALPH J. Ocns and 'CARL E. Honns, both citizens of-the United States, residing, respectively, at San Ber* nardino, in the county ofSan Bernardino, State of California, and San Francisco, in the county of San Francisco, State of California, have jointly invented new and useful Improvements in Auto Theft Signals, of which the following is a speciiication.

This invention relates to a bumping de vice, and particularly that form of bumping device which is adapted to be placed upon a vehicle wheel so that when the wheel is rotated upon a roadway said device will come into contact with said roadway and tend to lift the Wheel upwards and shake the vehicle to attract 4the attention of pedestrians. The invention is particularly applicable as an auto theft signal. The invention has for an object the provision of a bumping device which may be iirmly secured to a wheel of the commercially known disc type. Another object is the provision of a bumping device which may be attached to a wheel of any form and which when so placed on` said wheel cannot be moved from it position without releasing the same proper y.

In practicing the invention we provide a bumping device which includes oppositely bowed arms having upper ends directed toward each other, and the lower ends provided with projections.

The angularly directed portion of each arm is channeled .so as to engage with a spoke or with outstanding bolt heads ofi-a showing the locking member in inoperative disc wheel. The said arms are pivotally joined to each other adjacent the projections used for bumping purposes, and a locking means is associated adjacent the pivot point. Each of the proj ections is outwardly flared or. angled insuch a mannerthat in case the vwheel is rotated andthe projec-` tions come into contact with the roadway, all strain would be carried by the shouldered portion of the arms and by the boltjoining at the pivot point. By locating the lock member a little above or below the pivot point of the said arms all strain due to rotatingthe wheel with the projections engaging the roadway could be released from the lock and consequently would never endanger or render the lock inoperative. It is a known fault with the average theft signal that if the Vehicle to which the same is device attached should be moved, that the auto theft signal upon engaging the roadway would tend to strain the lockmember ren# ydering` it impossible to open said theft signal afterwards.

The invention has for further objects the provision of an improved bumping device which will be superior in point of relative simplicity and inenpensiveness of construction and organization, taken in conjunction with positiveness and effectiveness in operation.7 and bility.

The invention further consists in the novel and useful provision, combination, construction, krelative arrangement, mode of operation and inter-relation of parts, inembers and features, all as hereinafter 1described, shown in the drawing and finally pointed out in claims.

Referring with particularity to the drawing, the improved bumping device A includes arm members B eachv of which is provided with means C adapted toy be presented to the roadway. A lock member D general eiliciency and servicea` Specification of Letters latent. Patented Feb. 28p, 1.922. v

with an angularly directed portion., such angularly directed portion being formed with a channel 2, on one oit the arms and with a chamber 2 on the other arm which channel and chamber as shown in Figure l", is adapted to conine the ends of a bolt 3 extending through the disc 8 ot a' `disc wheel lThile the angularly directed portionl may be channeled as shown at 2 it is preferable lto enlarge the head portion so asfto have a` bore therein, Vand to leave the opposite angularly directed portion biiurcated or channeled as shown; thus when the device A is upon a. wheel it would be'iinpossible to remove the same because ot its grasping qualities upon the bolt ends. The arms B are each outwardly bowed as at 6 so as to form an annulus between the same so that the said arms may be adapted to extend around a tire 7 of the wheel. The angularly directed portion 1 engages opposite 'faces of the disc 8 located within the circumference ot the wheel. It is obvious that the channeled portion 2 will securely engage the boltr ends 3 and prevent movement` of the device A when it is in position upon the wheel as shown in Figure f1. Furthermore,

the channeled portion 2 might readily engage the spokes oiz a wheel in place of :the bolt-s on a disc wheel.

Referring to Figure 6 it will be observed that one of the arms B, as at 9, is provided with spaced cheeks 10 and `11 and that the other arm as at 12, is provided witha tongue portion 13 fitting `between said cheeks 1() and 11. A bolt 111 passes through a perforation extending through the cheeks and the tongue ior holding` the arms B in rela.- tion to each other. and likewise so that the arms B may be relatively movable. It will be seen by referring to Figure 2a as well as Figure 6, that the cheeks 10 and 11 are outwardly curved as at 15. The opposite arm B which carries the tongue 13 is so formed that the shouldered portions of the same as 16 and 17 are correspondingly curved to the portion 15 so that when any weight or pressure is exerted against the member C, the cheeks 10 and 11 will engage the portions 16 and 17 and tend to preventstrain at the pivot point, likewise taking all stress from the lock member. The means C associated with each arm B is so arranged that when the members are `ioined at the pivot point the means C subtend an angle a between the same, while the extremities of said means C as at 18 and 19 are located outwardly from the pivot point. The result is that it the means C come into contact with the roadway, the pressure beine; exerted at the points 18 and. 19 will tend to revolve the arms B inwardly so as to more tightly grip either `the spoke of the wheel :or the opposite 'faces oit the disc in case tho wheel is a disc wheel,

vice A in position thereon.

The lock member is illustrative only, and we do not wish to be restricted tothe particular iorm of lock shown; however, in Figures fl and 5 one oi' the arms B as 2O acts as a 'lock-carrying member, while the other arm acts as a lock-receiving member. The lock D inclu( es the usual opening 21 through which a key may be passed for operating the lock.v` One ofthe arms B as shown at 2O is provided with a bore or-socket 22 within which socket is coniined a coil spring 23. A bolt 24 is normally confined within the bore 22 and'engages at one end as 25 with an end of the spring Theloppositearrn B as at 26 is provided with a socket which is adapted to receive an end of the bolt 24 when the sockets 22- and 26 are in registration. l Such a registration will occur when the device A is in operative position, or in a position upon the vehicle wheel as shown in Figure 1. The bolt 211isprovided with a notched portion 27 and a stud 28 associated with the rotatable portionlof the lock D may engage the notched portion 2T and tend to retract the bolt 24 irom the socket 2G so that the arms B may be rendered relatively movable and the entire device A removed from a vehicle wheel. It is obvious that the particular arrangement shown will allow l point, although it may as readily be located above the pivot point. The particular method ot joining the arms B 4below the pivot point tends to relieve all strain from the bolt 241- in case, as has been pointed out, of rotation of ther vehicle wheel with the de- It is Obvious that the spring member 23 will normally urge the bolt 24 outwardly so that the bolt may be at all times ready to be shot into the socket 26 when the arms B are in proper position.

It will be seen that this bumping device differs from the forms no w on the market, in that it provides means for engaging the opposite face of a disc wheel or for engag ing a spoke of a spoke wheel.` This particular bumping device overcomes faults incident to the commonly known forms now on the market, by positively offering means whereby it is impossible to loosen the said l l bumping device :from the wheel` by, say, dcflatingthe tire. The device is likewise novel in that it provides for a stress-resisting means; a means for removing all stress from Vthe market, but is particularly kadaptable to the disc wheel type.

Itis obvious that many changes'a-nd modiizo the lock member and further, for an arm` site ends being angularly directed toward j each other, and means `for locking said arms in work-engaging relation.
